.thereof; and it is among Patented Oct. 13, 1931 UNITED STATES PATENT OFFICE HEAT EXCHANGING DEVICE Application filed December 4,

This invention relates to heat exchanging apparatus, and more particularly 1nse rt bodies or plates capable of being placed in a-wall to assist in the temperature control the objects of the invention to provide a construction affording a plurality of independent fluid passages.

' Another object is the provision of a device I the same time capable heat transfer and being at of sustaining considerable loads. Other objects and advantages will appear as the description proceeds.

To the accomplishment of the foregoing and related. ends, the invention, then, consists affording efficient of the features hereinafter fully described,

, embodying the invention, trative however of but a furnace wall showing my lmproved device in ta-ken on a place therein; Fig. 2 is a rear elevation of one form of the device; Fig. 3 is a horizontal section taken on a plane indicated by the line I'IIIII, Fig. 2;. Fig. 4 is an axial section plane indicated by .the line IV-IV, Fig. another-form; Fig. '6 is a horizontal section thereof taken on a plane indicated by the line VI-VI, Fig. '5; and Fig. 7 is a longitudinal section taken on a plane indicated by the line VII-VII, Fig. 6.

Referring more particularly to the drawings, there is shown in Fig. 1 a portion of a furnace wall 2 of masonry, firebrick, etc., the further detail being immaterial to the present invention. In the wall are temperature control plates 3, having pipe connections 5, etc. for inlet and outlet of fluid, header pipes (not shown) continuing onfrom these as desired to the source of supply and the fina discharge respectively. The plates 3 or essentially chambered hollow bodies are provided with passageways,'and have lower walls 6, upper walls 7, the latter being preferably arched where the load to becarried is 0011'.

The chamber system within involves rahty of lndependent passageways, one arranged to lie adjacent the forward or inner a plubeing end 10 and another lying rearwardlythereof. In the form shown in Figs. 2, 3 and 4, the

forward passageway 1s set ofi by a partition 11, and to the way system B,

thus the side walls,

laid out has lateral portions a,

The passage A as adjacent this entire system then formmg a loop from the rear around adjacent the side wall to the forward end, and thence back adjacent the other Openings 14 and 15 side wall to the rear. preferably tapped for pipe connections, provlde an inlet and an outlet for such passage. likewise openings 16, and by arranging the The passageway B has 17 for pipe connections,

b An additional opening 18, preferably placed at the highest point of the arch is desirable, being available charge or feed line; or culation 1s not requlred with a plug.

Apertured lugs 19 are of convenience in such handling of the unit as may be at any time necessary.

is again formed by baflle partitions 12', 13'

extending in a generally transverse direction, and openings 16', 17' provide inlet and outlet to pipe connections. Auxiliary opening 18', again, preferably at the highest point of the arch, allows of usage as a cleanout, or for additional circulation as required. In this construction, the conduits a have the further advantage of a positioning where especially well protected by the cooling water of the rear compartment.

It will thus be seen that plate constructions may be had in which independent passageways allow of fluid circulation, such that in the event of failure of one, functioning may be carried on with the remainder, and the construction is such furthermore as to make possible the carrying of heavy loads such as may be encountered in masonry walls of furnaces, with bosh plates and the like.

Other modes of applying the principle of the invention may be employed, change being made as regards the details disclosed, provided the means stated by any of the claims, or the equivalent of such, be employed.

I therefore particularly point out and distinctly claim as my invention earner verse bafies arranged to produce a sinuous circulation of the cooling fluid in said rear chamber, integrally-formed ducts passing through said partitions and forming an inlet and outlet suply for the forward chamber, and an independent inlet' and outlet for the rear chamber.
